WILLIAM EDENBORN, OF ST. LOUIS, MISSOURI.

MACHINE FOR COILING WIRE.

SPECIFICATION forming part of Letters Patent No. 480,564, dated August9, 1892.

Application Iiled November 16, 1891. Serial No. 412,054. (No model.)

T0 aZZ whom it may concern:

Be it known that I, WILLIAM EDENBORN, of the city of St. Louis, in theState of Missouri, have invented a certain new and useful Improvement inMachines for Coiling Wire, of which the following is a full, clear, andexact description, reference being had to the accompanying drawings,forming part of this speciication.

My present invention relates to certain improvements in the class ofwire-coiling maohines shown, described, and claimed in my applicationfor patent, Serial No. 373,809, tiled December 6, 1890, allowed June 15,1891; and Iny present invention consists in features of noveltyhereinafter fully described, and pointed out in the claims.

Figure I is a side elevation illustrative of my invention. Fig. II is avertical section taken on the line II II, Fig. I. Fig. III is a top orplan view of the table of the machine.

Referring to the drawings, 1 represents a table having an opening 2, inwhich fits and moves a cylinder 3, raised and lowered by a hydraulic ram4 or by other suitable means. The cylinder has grooves 5, receiving ribsor projections 6 on the table, by which it is held from turning, and aclosed upper head for preventing the Wire becoming tangled or enteringthe cylinder and rendering the coiling positive and certain.

7 represents an arm provided with a journal-box 8, which receives ahollow spindle or sleeve 9. The spindle is connected by gearing 10 to adriving-shaft 11.

12 represents a cone secured to the spindle 9 and carrying guide-tubes13, through which the wire passes from the feed-tube 14.

15 is a bushing inthe spindle 9, which may be turned to direct the wireinto either of the tubes 13. These parts 9, 13, and 14 are the same insubstance as the corresponding parts in my application referred to.

The cone 12 of this application diers from the cone of my otherapplication mentioned in that it has a flange 16, which embraces theupper end of the cylinder when the latter is in its upper or receivingposition.

The object of this invention is twofold:

First. It permits the upper end of the cylinder when the cylinder is inits upper position to entirely enter the cone, and thus avoids anypossibility of the wire as it issues from the tubes 13 being caught ortaking anyother course than being wound around the cylinder.

This in practice is of importance.

Second. The Iiangeprovides a surface larger than the Cylinder, uponwhich the last coils of wire are wound, these last coils being the wirecontained in the tubes after the end of the wire has left the rolls,(not shown,) and the friction of the wire in the tubes causes it to bedrawn very tight, so that when the cylinder is lowered to free it of thecoiled wire these last coils, being drawn over the larger movingsurface, will drop down onto the main part of the coil and will not becontracted upon the cylinder in cooling, as they would if drawn andwound upon it; and thus these coils do not interfere with the removal ofthe cylinder from the wire coil. It will be understood that as the conerevolves the last coils will not be permitted to shrink tightly on it,as they would if drawn upon the surface of the cylinder, which does notrevolve.

I claim as my invention- 1. In a machine for coiling wire, thecombination of a cylinder having a closed upper head, a winding-conesupported above the cylinder and fitting over the upper end of thecylinder, and means for moving the cylinder away from the cone,substantially as and for the purpose set forth.

2. In a machine for coiling wire, the combination of a cylinder having aclosed upper head, a winding-cone supported above said cylinder andhaving a depending I'iange 16, inclosing the upper end of the cylinder,and means for moving the cylinder away from the winding-cone,substantially as and for the purpose explained.

W'ILLIAM EDENBORN.
